I’m not an expert but when I want to see various platforms have a shot at appealing to a wider audience.
There are levels to the barriers to entry and barriers to use. Setup being hard or confusing is different from continued use being hard or confusing.
Every time I use one of these platforms I’m thinking “how much will I want to beat my head against a wall while trying to explain this to one of my clients over the phone.” Most of them are NOT tech savvy folks.
(We’re not at a stage even with Mastodon where I would suggest client’s set up accounts. Unless they were active on Twitter and trying to escape but most of them aren’t.)
